Hi Ben. I believe this is either the S351-18 or S390-18. The only difference between these two channel balances is the depth of the bottom nylon shoe, so compare both with your old hardware to see what matches best. See the image below for details. Also, please double-check the width; it should be 1/2", but let me know if it in fact differs before proceeding. For a stamp option, you'll choose 1730.

Well, if the depth is exactly 1", not 1-1/8", then the Series 351 would be the better choice. Let me know if you have any further questions. |
